."HYDROCABBON-MOTOR.

Specification of Letters llatent.

Applratinnmed May 18, 1914. Serial No. 839,308.

To all whom it may concern:

- Be it known thetlI Gnomes L MoCAIN, a

citizen of the United. States, und residentv of Detroit, A`Weyne countyfState ot Michigan, have invented certain new end useful Improvements in Hydrooerbon-liiotors, of which the following is e specification.

This invention relates to l'iydrocarbon motors and particularly; to the crunk o se construction.

In designing hydroom 1 motors for vehielo use it ,is desireiuio t 1., motor be hung low possibi"- ohessis to keep the center of grew' uowf'i and utthe same time considere'oie ele: .ee the y'wheel is desirable. eferebly therefore, if the y'wneel is inclosed, the casing should extend below the flywheel only suiicient to cover it, end :my further extension takes directly from th l eleerenee..

It is desirable in ve noter construction that the motor clefs shaft and been ings shall be readily efr: yde. y

Une of the A(.bjeets oit 'the present invention is to produce e motor having a, removprovided with ineens for ett-eohmer ng While at the same time it provid maximum of reed olea-rance when the motor is mounted inaJ chassis.

This and other objeets 'the invention description teken in connection 'with the drawings which form a, port ofthe s'iecieation, and in Whicl'1':-.-'

Figure 1 is a, sidev elevation of: si motor embodying the inyen'tiemperts 'being broken away;

Fig; 2 is V:.t-'seotion ou the line Pf-2 of Fig.'

ternel groove threededf into' thelange 26. @Thron `t will be seen the tftlrisv cover may vbe dropped and-the entire inside of the crank case, including vthe crank shaft and bearings, is exposed and accessible.

'The'orank shaft' 15 extends through the rear Wall or partition 18 formed as apart of the crank cese and huso flywheel 19- secured thereon." 'From the orankshziftor iiyw'heel the power of the motor is'A transmitted through e clutch 20' of any desired form, a shaft 21, and change speed gears V22, to the driving Wheels ofthe vehiclen The 'flywheel 19 is inclosed or housed by au enlargement or extension 23 of the zink cese, this housing being extended some -ut beyond the flywheelond-beingf 'provided with ineens 'for ettfiehment tofu veasing 21 which is edapted to inelose'fsmdsupport the clutch or gearing or both. it will be seen that vthis flywheel housing is formed es en integral part of the-upper and lower ports of `thev crank case und that it is sepa-rated .from the interior of the crank cese by the int rgrel end'well 18, seid end'wnilolosely surrounding the crunk shaft 'by .a Y' packed joint as et25'-toprevent the oil infthe crank oase getting-into the flywheel and clutch housings.

The rear-"end of the housing 23,'fwhioh is of 'substantially cylindrical form where it surrounds the iywheel is formed:v with an annuler llenge 26 turned inwardly as shown in. the drawings. In the upper part "of the housing this flange is shown' solid, v:is it is also in the lower part 1n the orm of the invention shown in Fig. 3,-'butin the lower part-of the'h'ousingshown in Fig. 1 the flan-gel-is formed Withan annular ex- 2'? Whicl'i in faot- -1nakes of it ai renttent Harige. The` 'casingg24 is formed :with 'a flangedforwa'rd part 2S edapted to fit thev flange 26' and bolts 29:- seoure the casing to the flange.l a Inf the form shown in `Figi 1", through bfolts meyjbe 4used with nuts 30 which 'are )arranged 'in the groove 27- zmd tlu-u'eforel accessible, roni the outside of the casing. Fig. 3,' studs or plain bolts* may be 'used as shown endl gh bolts are desirable whenv thehousing 231s, mede of soft nietl such aluminum because of thei'poor'holdi-ng e'ect of bolts f threaded into thotinetel. ll', will be understood that. through bolts mftybc `used in the solid inturned'zinge 'of the upper Apuri', `because the casing 24 may be secured thereto before the lower part is assembled, whereby the interior of the housing is accessible. It will be understood further that the casing 24 will be wholly supported from the upper part 12 of the crank case, as will the crank shaft and flywheel, when the lower part 13 is removed for cleaning or examination.

Y turned Because of the form of the attaching means between the casing 24 and the part 13, the road clearance is left at its maximum, there being onl enough of the housing 23 under theflyw Veel to cover it.

t will be understood that the invention is not limitedto the specific form shown herein, but is capable of modification in ,various ways wit out departing from the spirit or scope of the claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent isz- 1. In a hydrocarbon motor, having a flywheel, the combination with a crank case having an enlarged portion surrounding the flywheel and an inturned flange thereon in aplane at ri "ht angles to the longitudinal axis thereof eyond theflywheel, of a casing secured to the crank ,case at said flange.

2. In a hydrocarbon motor having a flywheel, the combination with a two part crank case having an enlarged portion surroundin the Wheel and an annular inangles to the lon 'tudinal axis thereof eyond the ywhee of a, casing secured to the'V crank case at said flange Vand supported thereby.

3. In a hydrocarbon motor, in combination a crank case comprising an upper supportin part and a lower cover part, a crank shaft aving bea-rin supported wholly by said u per art an having a flywheel at one en sai upper and lower parts extend- :ing beyond and covering said ywheel, and a casing .so secured to both arts of said crank vcase beyond the flywhee as to permit the lower part to be removed without disturbingthe attachment of the casing to the upper part;

4. In a hydrocarbon motor in' combination, a crank case comprising an upper supportin part and a lower cover part, a crank shaft aving bearings supported wholly by said upper part and having a flywheel at one end, said upper and lower parts'extending beyond and covering said flywheel and having an nnular'inturned flange, a casing beyond t e flywheel, and means for securing said casing to both parts of the crank case so that the lower part may be removed without disturbing the securing means of the casing to the upper part. i
